Canon has developed Blue Spectrum Refractive (BR), a new optical element for use in camera lenses that corrects chromatic aberrations at an extremely high level to achieve superb imaging performance.
Canon claims that the BR optical element offers characteristics that significantly refract blue light, which lies within the short-wavelength range, to achieve impressive levels of chromatic aberration correction for outstanding imaging performance. The BR optical element, positioned between two glass lens elements to create a BR lens, will make its debut in the new EF 35mm f/1.4L II USM wide-angle fixed-focal-length lens, which is scheduled to go on sale in October 2015.
Natural light, or white light, comprises a spectrum of wavelengths, or colors, each of which realizes a unique refractive index when passing through a lens. As all colors do not converge on the same point, this disparity causes chromatic aberrations, or color fringing, to occur in an image.
Canon also today announced the the EOS M3, a compact interchangeable lens digital camera created for enthusiast photographers.
At the heart of the EOS M3 camera is Canon?s latest digital imaging technologies, including the company?s high-resolution 24.2 megapixel APS-C CMOS image sensor and its most advanced image processor, DIGIC 6. Combined with super-fast AF performance, thanks to a new 49-point Hybrid CMOS AF III Autofocus System, this digital camera gives photographers the freedom to capture the beauty of movement. Advanced photographers will find everything they need at their fingertips, with DSLR-like dials and control, as well as access to the entire lineup of more than 80 Canon EF, EF-S and EF-M interchangeable lenses, all shrunk down into a compact, mirrorless body to take with them wherever they go.
EOS camera technologies built into the EOS M3 camera include:
- 24.2 Megapixel APS-C Canon CMOS Sensor, with a sensitivity range from ISO 100 to 12,800 (expandable to 25,600 in H mode) paired with Canon?s proprietary DIGIC 6 Image Processor to capture high-resolution photos and Full HD videos.
- 49-Point Hybrid CMOS AF III Autofocus System for fast autofocusing of stills and videos, up to 6.1x faster than the original EOS M.
- Front and Rear control dials for full manual operation and customizable functions as well as improved ease of use.
- Touch Screen 3.0-inch tilt-type (180 degrees up/45 degrees down) ClearView II LCD screen (approximately 1,040,000 dots), perfect for quick focusing and shooting, easy menu navigation, and simple viewing of images and videos.
- Built-in Wi-Fi and NFC for streamlined photo sharing and wireless remote control.
Canon?s EOS M3 Digital Camera is scheduled to be available in early October 2015 for an estimated retail price of $679.99. An EOS M3 EF-M 18-55mm IS STM lens kit will be available in the customer?s choice of black or white for an estimated retail price of $799.99. Additionally, a two lens kit featuring the EOS M3 digital camera with the EF-M 18-55mm IS STM lens and the EF-M 55-200mm IS STM lens will be available for an estimated retail price of $1,049.00.
The following Canon lenses will also be available in early October:
- EF-M 11-22mm f/4-5.6 IS STM wide-angle zoom lens for an estimated retail price of $399.99
- EF-M 22mm f/2 STM compact prime lens in silver for an estimated retail price of $249.99
- EF-M 55-200mm f/4.5-6.3 IS STM telephoto zoom lens for an estimated retail price of $349.99
